To all whom it may concern:

Be it known that I, MICHAEL PARIDON, a citizen ofthe United States, andresident-of Barberton, in the county of Summit and State of Ohio, haveinvented certain new and useful Improvements in Mechanism for FeedingBox Members, of which the following is a specification.

This invention relates to mechanism for feeding box members (eithertrays or covers) in an orderly manner. to suitable receiving devicestherefor, having reference more particularly to mechanism whereby tworows of trays and two rows of covers are directed toward the conveyor ofa box "filling machine, from opposite sides of the latter, and wherebythe leading trays and covers of the respective rows are introduced intospaced-apart receiving portions of the conveyer, such, for example, asdescribed in Letters Patent of the United States, Paridon No. 1,360,438,dated November 30,- 1920.

The principal object of my invention is to provide mechanism-of vsimpleand efficient construction whereby box members emerging ina row from asuitable supply hopper,

and resting upon their long narrow sides, are automatically divided intotwo rows and the members of each of the latter advanced to the vicinityof the conveyer of the filling machine and in proper position forintroduction successively into spaced-apart receiving portions of thesaid conveyer.

The embodiment of my invention herein illustrated comprises a troughstructure haying two guide paths which diverge from the supply hopper tothe conveyor and are of such construction that a row of box members isdelivered from the hopper into the proximate end of the trough andthereby diverted 'into and advanced along the respective paths, which"advancing box members are progressively deflected to proper position fordelivery to the conveyer. The invention also comprises novel features ofconstruction and combinations of parts which will be hereinafterdescribed and claimed. In the drawings Figure 1 is a plan of a ortion ofa boxfilling machine equippe with delivery mechanism embodying myinvention, aportion of the supply hopper being shown in section. Fig. 2is a longitudinal vertical section through the machine, as on'the line2--2 ,Fig. 9 is a transverse section of the spaced 'apart guides at thedelivery end of the trough. I

Fig. 10 is a perspective View of the trough.

Referring to the drawings, 11 designates the table of a box fillingmachine; 12 the upper run of the tray-and-shuck conveyer, and 13 one ofthe intermittently actuated sprocket wheels for the conveyer. Arrangedon the table, adjacent and at right angles to one side of the conveyer,are two spacedapart guide channels 14 each of which is adapted toreceive box members, (as a) in endwise relation to each other. Mountedto reciprocate in and longitudinally of the nected by means of links 20with arms 21.

l rising from a rock-shaft 23 which has its bearings in brackets 24extending from the side of the table. The outer end of the rockshaft isprovided with an arm 25 having a roll in engagement with an appropriatecam groove 26 formed in a suitably-disposed driven gear wheel 27,whereby during the rotation of the latter the rock-shaft is actuated.and the plungers are simultaneously reciprocated toward and from theconveyor, in such a manner that the leading box members contained in theguide-channels 14 are pushed into the adjacent receiving spaces of theconveyen; all as fully set out in Patent No. 1,360,438 aforesaid.)

28 designates the delivery end of a supply hopper from which the boxmembers, resting upon their long narrow sides, are discharged in a row,which hopper is preferably of the general construction illustrated inpatent Paridon and Weaver No. 1,086,210 dated February 3, 1914. Thishopper includes a rotary drum 29 into which the box members are placedin mass and therein agitated,

and a pair of oppositely-rotating helicallyformed rollers 30 arrangedwithin the drum and operative to receive the said box members, disposethem in endwise relation to each other, and resting upon their longnarrow sides within a trough 31 which extends through a stationary endhead 32 of the hopper. A travelling feed-chain 320 extending along thebottom of the trough 31, advances the boxes to and through the deliveryend of the trough.

The supply hopper is spaced a suitable distance from the guide-channels14, and a shallow trough 33 embodying my invention is interposed betweenthe hopper trough 31 and the respective channels. This trough 33, in itspreferred construction, comprises a bottom 34 having side walls 35extending throughout its length. The side walls are flared outwardly anddiverge from a plane adjacent. the narrow receiving end to a planeadjacent the wider discharging end of the trough, such walls beingsubstantially parallel at the respective ends. The upper surface of thebottom is inclined downwardly and outwardly from its longitudinal medianlineto the respective side walls,

throughout the length of the flaring divergent portions of the walls, asseen in Figs.

4 to-8, inclusive, and 10, such oppositely in-.

respectively, of the trough, as seen in Figs. 8 an 9.

The trough 33 preferably declines from the discharge end of the hoppertrough to the guide-channels 14 adjacent the conveyer; the narrowreceiving end of the trough 33 being in close proximity to and beingsubstantially the same width interiorly as the hopper trough, andthe-discharging end of the trough 33 being of such width that. the widerends of the side walls 35 are in close proximity to and in longitudinalalinement with the outer walls'of the respective guide channels. .1

The trough 33 has capacity for its longitudinal vibration, andaccordingly the receiving end of the trough rests on a bracket 38extending from the stationary end head 32 of the hopper, and thedischarging-end of the trough rests on the plunger guide bracket 17adjacent .the conveyer. Any

suitable means for vibrating the trough may be employed. In the presentinstance, the bottom'of the receiving end of the trough is providedwitha socket piece 39 which re-- ceives an eccentric 40 on the upper endof a vertical shaft 41 having its bearings in the bracket 38 and in alower bracket 42. The foot of the shaft bears a bevel pinion 43 in meshwith a bevel wheel Mon a driven shaft 45 mounted below the hopper, andhence during the rotation of the latter shaft motion is transmittedtherefrom to the vertical shaft and its eccentric in a manner to imparta rapid longitudinal vibration to the trou h.

By the oregoing described construction it will be seen that thebox-members, resting upon their long narrow sides and placed end to'end,pass from the feed trough of the hopper into the narrow receiving end ofthe vibrating trough and are caused to descend the latter. In the caseof trays the bottoms of some of them will be at one side of thevibrating trough, (as in Fig. 3), while the bottoms of others will be atthe opposite side of the trough, and hence as the trays progress uponthe central crest of the vibrating trough they will be tilted by theirheavier bottoms toward the side or sides of the trough adjacent suchbottoms, and as the tilted trays continue their descent they willfinally gravitate, bottoms downward, upon the proximate inclined floorsurfaces and ,hug the respective side walls of the trough until suchtrays pass to and upon the flat floor portion 37 at the discharging endof the trough. At this stage the leading trays of each row will beup-right, and whilein. suchposition they will enter the guide-channelsabove the adjacent plunger 15, and passing thence to the reciprocativepath of'the plunger as seen in Fig.2, they will be successively pushedinto the-receiving spaces of the conveyer.

In the case of the delivery of covers or shucks from the hopper into thereceiving end of the vibrating trough one or the other of the longnarrow sides of each cover will rest upon the floor of the trough, andas the covers descend upon the inclined surfaces of the trough some ofthe covers will be tilted toward one side and others toward the oppositeside of the trough in such a manner as to gravitate toward therespective side walls aiid assume a flat lying position upon the bottomof the trough pre-' paratory to their entry into the guide-channels 14and their final transference into the receiving spaces of the conveyer.Y
